Quorum disks on HP 3PAR storage arrays
The Storwize® V3500 clustered system requires managed disks (MDisks) that are quorum disks for system metadata storage.
The Storwize V3500 clustered system selects disks that are presented by the HP 3PAR storage array as quorum disks. To maintain availability with the system, ideally each quorum disk should reside on a separate disk subsystem.
